摘要：
Mould (1) for injection moulding of a flexible shell for use in body implants, said mould comprising: a mould core having a stalk (6, 7) and a convex bulbous element; and two mould halves (2, 2'), wherein each mould half is arranged for mating with the other mould half at respective confronting surfaces, each surface comprising a concavity forming, in the mould halves, a mould cavity (3, 3') for mating with the bulbous element; wherein said mould core comprises: a first stem (7) forming a first portion of the stalk and a proximal portion of the convex bulbous element; a second stem (6) forming a second portion of the stalk and a distal portion of the convex bulbous element; arranged such that one of the stems (6) is displaceable relative to the other stem for opening a gap (17) at the bulbous element, between the stems, for the injection of an ejection gas to eject the moulded shell. Moulding method using said mould and flexible implant shell moulded by said method.
